Can the heartscan be used for diagnosis and monitoring of emergencies in general practice?

Introduction: Mostly, it is impossible to establish the type of arrhythmias, based on signs and symptoms only. An ECG device is not always within reach. We presumed the heartscan, a handheld wireless device, to be of value to a GP in emergency situations.

Effect of dietary fat sources on fatty acid deposition and lipid metabolism in broiler chickens.

The hypothesis tested was that dietary vegetable fats rich in saturated fatty acids, when compared with a vegetable oil rich in linoleic acid, increase fat deposition in broiler chickens and affect synthesis or oxidation, or both, of individual fatty acids. Diets with native sunflower oil (SO), a 50:50 mix of hydrogenated and native SO, palm oil, and randomized palm oil were fed to broiler chickens. Intake of digestible fat and fatty acids, whole body fatty acid deposition, hepatic fatty acid profile, and hepatic enzyme activities involved in fatty acid oxidation and synthesis were measured.

The mitochondrial citrate carrier: metabolic role and regulation of its activity and expression.

The citrate carrier (CiC), a nuclear-encoded protein located in the mitochondrial inner membrane, is a member of the mitochondrial carrier family. CiC plays an important role in hepatic lipogenesis, which is responsible for the efflux of acetyl-CoA from the mitochondria to the cytosol in the form of citrate, the primer for fatty acid and cholesterol synthesis. In addition, CiC is a key component of the isocitrate-oxoglutarate and the citrate-malate shuttles.

Enigmatic effect of cellular ATP on fatty acid biosynthesis. Stimulation by moderate decrease and inhibition by increase of cellular ATP.

The cellular ATP concentration was tested for its effect on fatty acid biosynthesis from glucose in hepatocytes. ATP was manipulated by adding increasing concentrations of cycloheximide, amytal, atractyloside, 2,4-dinitrophenol or adenosine. A slight decrease in cellular ATP coincided with a stimulation of fatty acid biosynthesis whereas a further lowering of cellular ATP resulted in a gradual inhibition.

Fatty acid digestion and deposition in broiler chickens fed diets containing either native or randomized palm oil.

The hypothesis tested was that randomization of palm oil would increase its digestibility, especially that of its palmitic acid (C16:0) component, with subsequent changes in the fatty acid composition in body tissues. Broiler chickens were fed diets containing either native or randomized palm oil. Diets with either native or a 50/50 mix of native and hydrogenated sunflower oil were also fed.
